This is the net of a cube. What is the volume of the cube in cubic centimetres?
We know this is a net of a cube. We have to find the volume of this cube. But we’re not given the measurements of the lengths of the sides. But we are told that the total lengths of four of the squares is 20 centimetres. So if we divide 20 by four, this will tell us the length of one side. 20 divided by four is five. So now we have the measurements to mark on our cube.
To calculate the volume of a cube, we use the formula length times width times height. So we need to calculate five times five times five. Five times five is 25. And 25 times five is 125. Four 25s make 100. And one more makes 125. And we’re asked to write our answer in cubic centimetres.
So the volume of the cube is 125 cubic centimetres.
First, we calculated the length of one edge by dividing 20 by four. Then, we calculated the volume by multiplying the length times the width times the height. Five times five times five is 125 cubic centimetres.
